Web IDL doesn't say how interface prototype objects are created 
algorithmically, with any defined order of property creation.  It just 
says that properties for operations/attributes/constants must exist on 
the object.  Without defining that order, we don't get consistency 
across browsers.  So we would need to define what that order of property 
creation is to make the enumeration order any more specific than it is 
at the moment.
